Conditions at Ozaki in January

January: The Winter Monsoon Bottleneck

January is locked in the heart of the northwest monsoon, with WNW winds blowing a combined 23.1% of the time and NW/NNW adding another 28.2%. On paper that offshore flow is exactly what Ozaki wants, but in practice it is frequently too strong, leaving only a 6% window of truly ideal conditions. The swell field is small, averaging just 0.6m (2ft) with an 8.6-second period, and most energy is a mix of ESE, SE and E directions that do hit the beach, but remain under 1m. You will mostly find grovelly 2ft waves, with occasional clean 2-3ft sets when a weakening low pressure system delivers a burst of longer-period SE swell. Air temperatures sit around 8.4°C with water at 18.9°C, making thick rubber the standard uniform.
